Q: Give the columnrange different colors I have built some HighChart and I would like to give the 3 columnrange different colors (And not just blue as the current highChart Please see the jsfiddel link below)  to make it simple for persons to see the difference when taking a look at my HighChart.

Highcharts.chart('container',
 {
     chart: {
         type: 'columnrange',
         inverted: true,
         height: 200,
         spacingLeft: 30
     },
     credits: {
         enabled: false
     },
     title: {
         text: null,
         style: {
             "fontSize": "10px"
         }
     },
     subTitle: {
         text: null
     },
     legend: {

A: You can replace the each point array with object and declare separate color.
{x:1, low: 1483337940000, high:1483338000000,color: 'red'},

A: Zones would probably be better for you here. That way the color belongs to the chart not the data. Zone value represents up to next x range.
Here's the example for Highcharts docs:  
Highcharts.chart('container', {
    series: [{
        data: [-10, -5, 0, 5, 10, 15, 10, 10, 5, 0, -5],
        zones: [{
            value: 0,
            color: '#f7a35c'
        }, {
            value: 10,
            color: '#7cb5ec'
        }, {
            color: '#90ed7d'
        }]
    }]
});
